IMPROVEMENT IN MILK-carts.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it may concern Be it known that I, JOHN COCHRAN, of Purdys Station, in the county of Westchester, and State of New York, have invented a new and useful Improvei section o f my improved Similar letters indicate corresponding parts.

My invention relates to cans Afor transport-ing milk (although other articles may be transported in them) from the farm or dairyvto the place where the milk is to be dispensed or used.

Milk-cans are subjected and exposed to rough usage and handling, and it is necessary, therefore, that they possess great strength, and be capable of enduring severe blows and shocks without being broken thereby.

My invention enables me to produce a can which will resist rough usage with good results, and which can be made with greater facility than cans, as ,now constructed; and

It consists in a bottom, with a rim which is retained by a shoulder, and a confining flange, on which latter the can rests.

It further consists iu the peculiar construction of the top or cover.

The letter A designates the body of my can.

It ismade with a bottom, B, which is inserted from below, and confined between the inner-shoulder C and the bottom flange F, between which points the body A is slightly enlarged in diameter, so'as to admit of the formation of said shoulder C, but the shoul der C may be made without increasing the diameter of that part of the body A which is below it. lhe bottom B is made of such a size in its diameter as that it cannot pass above said shoulder C, which, therefore, forms a stop or upper bearing for the edge ofthe bottom to rest against.

From the perimeter or edge of the bottom B extends a cylindrical shell, E, whose length varies accox-ding to the distance between the shoulder C and the lower edge of the body A of the can, being less than that distance to allow the said edge to be turned over, as shown. The lower end of the shell E is open, and, therefore, the combined bottom B and shell E form what may be called an inverted cupI or vessel. The shellE gives stillness to lthe bottom', and also strengthens the lower part of the can, and gives thereto an interior support, which is very beneficia-l in enabling it to bear violent usage, without being soon bent and destroyed.

In constructing my improved can, I form the shoulder C .all around Ithe interior of the body A, at the proper distance from its lower edge, and then insert the bottom piece B E from below, pushing the perimeter of the bottom close up against the shoulder C.

'I then confine and lock the combined bottom piece B E in place by turning the lower edge of the body A of the can over upon the lower edge ofthe shell E of said bottom piece, so that the turned edge forms v a flange, F, whereby I not only lock the bot-tom piece in place, but thicken and strengthen the lower edge of the can.

The joint formed between the bottomv B and the shoulder C is made tight by soldering the same, which may be done by introducing solder within, and exposing the exterior of the can opposite'the joint to heat, and turning it over the fire until the joint is perfect. The joint at F can be also soldered, if desired.

My improvement can be applied to securing bottoms to cans and vessels, where such bottoms are simply disks or plates, without the extension E, in` which case the' distance between the shoulder C and the overturned edge F must be only equal to the thickness of the bottom. I

Another part of my invention consists in a novel construction of the cover.

The cover consists of a top or hood, K, which over-` Y laps the mouth H, as usual, andv of a circular lip, L, which extends from the under side of the hood K 'downward a sufficient distance lto allow it, when the cover is on, to enter the narrow neck M ofthe can. The lip prevents the escape of any of the contents of the can, and the hood protects the mouth.

The lip of the cover is exposed to great` strain in the act of closing the can, and it is thereby frequently broken away at the joint N, where it is united to the hood.

My improvement is intended to strengthen this joint, by forming a circular shoulder, O, in the inte rior of the hood K, in such aposition as to form a bearing for the edge of the lip L, where it joins the surface of the hoo This construction enables the joint to resist violent strains and shocks, and also facilitates the making of the cover, because the shoulder forms a guide in adjusting the lip to its place before soldering the 'parts together.

In this example I have formed the shoulder O by depressing the central part of the top or hood Kfrom der O and lip L, constructed substantially as dewthout, and the. shoulder thus formed serves as a, scribed. guide for adjustiug'and soldering the lip. l This specification signed by me this 10th day of JOHN COCHRAN.

What I claim as new, and desire to secure by Let- December, 1869. ters Patent', isf- A 1. The bottom B, with rim E, in combination with shoulder C and the confining flange F, on which the Witnesses: can rests, substantially as set forth. W. HAUFF,

2. The cover, consisting of the head K, with shou1- E. F. KASTENHUBEE.
